You can change the version number in the registry to the most recent one to make this game run. I just did that.
Thing is I don't know if you can run this game with CF or if it just uses a single card. If it's the latter, then it's gonna be too weak. I have a single 6970 and it's just barely enough to set some settings at medium (to reduce flicker) with the sacrifice of overclocking it with giving extra voltage and reduce the resolution to 75%... While maintaining 28-42 FPS... And my card is a bit stronger than yours...
Now, I wouldn't recommend it to you, unless you know how it works to use the registry. You have to open your driver software and check the current driver version. In my case it was 15.301.1901-160226a, your version will be most likely different.
Then, what you do is open the registry, and press CTRL+F and you search for your driver version. In my case what I did is left the -160226a, as it wasn't descripted in every string like that, so I searched for 15.301.1901 (again use your version to search or you will find nothing).
Oh I should mention the most current WHQL one is 16.30.2311-160718a.
So, whenever I found a string that was 15.301.1901-160226a, then I replaced it with 16.30.2311-160718a. When a string however was something like 15.301.1901.000 for example, then what I did is just 16.30.2311.000. So let the format be how it was. Get it? And just keep pressing F3 after changing each string until a box appears that it can't find anything anymore. Now you should be able to start this game.
I'M NOT RESPONSIBLE FOR ANY DAMAGE YOU CAUSE TO YOUR COMPUTER. You should know if you can handle this or not. If you think you can't, then don't. Simple.
